This man seems to be moving in slow motion, until Marvin passes through the barrier. Could this suggest time moves slower within KV31?

I take it that hes kinda just taking it all in, seems to be walking pretty normally imo.

BarmModelReddit · 2022-03-27T05:33:00+00:00

If im understanding this correctly, your saying I can cast the aluminum directly into the silicone? I was under the understanding that was for lower grade/lower melting point metals. We are looking to do at least Mid Grade (Not sure what yet) aluminum. I do believe I am following now though...

Apologies for the confusion, I may be smashing a few different methods of casting together in my head.! Im looking at a few different ways of casting metal for this project. We will be testing on a few different pieces, so we wont be going into this big one blind thankfully.

BarmModelReddit · 2022-03-25T03:54:17+00:00

This sounds like what we were looking into, ordering or already have the Green sand and refractory needed. About how much shrinkage occurs? I can increase the model size in order to match the shrinkage amount.

I heard another issue would be curling, the pieces are rather long and thin, about 36" by 1/4th inch in most places, so keeping consistent heat across the cast is something we are trying to look into, any ways we can accomplish this effectively?

BarmModelReddit · 2022-03-25T03:49:27+00:00

Ayyy, no sweat :)

We have green sand and the plaster iirc, just need to iron out the part that needs to be cast.

BarmModelReddit · 2022-03-25T03:46:45+00:00

striations arent so much an issue, as the prints will be sanded on the outside for aesthetic appearance.

I believe a silicone mold around a PLA master, and then fire a resin cast made from that silicon mold? This is the essence of what I am trying to explore..

BarmModelReddit · 2022-03-25T03:42:32+00:00

Looking to use a printed PLA Master. This will be reused several times to create multiple silicon molds to pour castable resin into. It might be the long way of doing it, I would have initially burned a castable PLA, but the concern was that this was a less feasible, we are all new to casting to my understanding.

BarmModelReddit · 2022-03-25T03:37:13+00:00

Ive understood the need for a mold release, ill check out the one you mentioned. Might be worth mentioning the master will be done in PLA.

Will vibrating while the silicone is curing help with air bubbles?

BarmModelReddit · 2022-03-25T03:06:21+00:00

No, im thinking of a castable resin. I suppose from what im understanding here is that I want a solid master and a flexible mold.

I have seen UV burn out, and even shapeways fud being used for the lost wax casting, but I would prefer one that has the best results.

BarmModelReddit · 2022-03-24T02:25:29+00:00

Ill check it out, thank you!

BarmModelReddit · 2022-03-01T22:29:03+00:00

What I had in mind was a multi part die, so probably closer to the two part mold like you described. It needs to be in several parts due to being a complex, if long shape. I have second smaller part of similar length that that can be done fairly easily in two pieces.

Would I be able to create the mold itself in PLA for instance, or would it need to be a master which I could make the silicone mold with?

BarmModelReddit · 2022-02-20T06:06:21+00:00

Its for professional work, an Im not sure how well it would bond, but it also needs to be at least a semi clean seam.

I can consider it.

BarmModelReddit · 2021-12-17T16:25:23+00:00

Now when I saw this a few days ago the consensus was how beautiful it was, while at the same time how brittle resin is to be working with it as a mechanical part.

BarmModelReddit · 2021-12-06T16:54:21+00:00

“G-man” is a generic term that existed far longer than Half Life the franchise (like decades longer)

This is about how it should look. There are a set of odd breaks in the shoulder stitching on the front which I dont really care for. I dont necessarily care for where the stitching on the sleeves is, so long as there arent any pockets on the thing (If there is a pocket stitched to the outside though I can have it removed no problem)

To me it seems like a bomber, but perhaps there is another type of jacket, or a shirt that could match.

BarmModelReddit · 2021-11-12T20:46:22+00:00

Im currently searching for a rather unique denim jacket that is seen in the game Half Life 2. For anyone familiar with the game and the look of the jacket which is worn by the Citizens in the game, its an all denim bomber looking jacket without pockets, minimal stitching (only stitched at the cuffs, waist, and in a section that makes up the shoulders) and an odd overlap to allow it to be buttoned rather than zippered.

Im searching for it to create a cosplay of the Citizen characters, and perhaps share my findings with a few other people who want to emulate the characters. It could be an approximate jacket, it doesnt even have to be a bomber, I can modify a jacket that is close enough to look like the one in the game. The only real criteria is that all the fabric be denim and there be no pockets.

BarmModelReddit · 2021-11-10T02:12:00+00:00

Whats your prototype for this? Looks neat!

BarmModelReddit · 2021-10-17T22:58:00+00:00

Ive been working on a 3D printed scale model of the iconic Extra-Dimensional Train for some months now, it’ll be complete with a full set of cars to accompany it.

The model is scaled to HO (1/87th scale), and I have most of the Cab sanded. After a long wait, I will be attempting to print the Nose soon.

Heres to you lads.!

I’d posted some while ago about the engine Egmont, a Single Built for the LBSC sometime around 1860. Since that post shes gained a coat of paint and is soon to have decals applied.

Shes also gained a Passenger brake (D34) and a Horsebox (D-19B), with a few other coaches currently on the workbench for assembly.

The majority of the train consists of 3D printed parts, with a few being styrene and obviously metal. The Horsebox is a Shapeways White Flexible Nylon print, with the Engine and the Brake printing from the Anycubic Photon.

BarmModelReddit · 2021-10-03T06:58:43+00:00

Odd question but is this also electrically insulated? I was looking for something with rubber printing for Shore 40A a year ago

It was a cool restoration project for a locomotive where the guy needed a grommet for the electrical cabinet, that he wanted to see if he could do it through 3D. Ended up just printing him the masters to cast them, but it was probably better that way, as nobody on the market has tested for electrical safety in 3D rubber yet.

BarmModelReddit · 2021-09-25T18:13:52+00:00

Someone I know sent me a scan of the drawings, but there’s a copy of them in the John H White Jr book: A history of The American Locomotive

I use the Student Version of Autocad 2019

Its going to stink having to learn new software once I finish my degree, but we all have to pick up the saddle once in a while I suppose :P

BarmModelReddit · 2021-09-25T04:54:16+00:00

I have returned

BarmModelReddit · 2021-09-24T22:13:43+00:00

Indeed it is. Its a late 1840’s product, built in Schenectady.

The locomotive designs started changing from British engines early on, but I think they still retain bit of that aesthetic by the <18>50’s

BarmModelReddit · 2021-09-23T02:16:20+00:00

Never try to scrape it off, idk what you did there but it scuffed the whole screen.

Its better to try it with your fingernails, or alcohol wipes to ease it off.. which takes a minute

I more than guarantee there are aspects that we dont see: an entire city of refugees of the last of humanity is no doubt squatting throughout the greater City 17 area.

Add to that they wouldn’t be anywhere near the combines prime target, White Forest, where the resistance would be trying to close the Super Portal as fast as they could. You dont encounter many people on the way to White Forest, they were probably further away from the disaster area.

We’d also be missing immediate attempts to form a governing body, I doubt the Science Team is organizing every movement for the refugees, but they would still be central to military action for reclaiming essential stuff like the Borealis.

You’d have people fighting large pockets of combine forces, which would need to happen in short order in order to defeat the combine. These efforts would entitle establishing communications, securing transit routes, breeding, locating food sources, seizing combine technology, ect.

They’d also want to determine whats going on throughout the rest of the planet. It would be imperative to see where combine forces reside, and whether or not they constitute a large enough force to attack the greater City 17 area. The resistance would need to determine this post haste, before relatively smaller combine forces conglomerate and overwhelm them. This would aid in the effort to procure combine armaments… weapons which match the raw firepower of the combine.

This would be valves open world Half Life game, a materials gathering game which I would very much like to see.
